Obesity and cancer: Relevance of DNA damage response.

ABSTRACT: Obesity is a non-communicable, multifactorial disorder that has steadily emerged as one of the major global health concerns. It significantly increases the risk of diabetes, cardiovascular diseases and cancer. In obesity, the accumulation of excess fat causes increase in the circulatory levels of adipose tissue-specific hormones (adipokines) and exacerbates carbohydrate-fuelled metabolic stress. These factors promote oxidative and genotoxic stress, resulting in chronic inflammation. Moreover, obesity-related factors contribute to increase in DNA damage and disrupt the DNA Damage Response (DDR), thereby promoting genomic instability. Consequently, obesity may facilitate a complex, multi-step process of cellular transformation and cancer progression. However, the mechanisms linking obesity-a
